title = "Using wenner probe resistivity to estimate chloride diffusion coefficients in concrete",
abstract = "This study compared and contrasted the surface concrete resistivity test measured with the Wenner probe, with the chloride conductivity index (CCI) test in terms of their application in the design of reinforced concrete (RC) structures. Chloride diffusion coefficient and time to corrosion initiation (ti) were estimated using diffusion-based and resistivity-based service life prediction models. The resistivity-based prediction model results in ti values similar to those for the diffusion-based model only for CEM I and slag concretes at 0.40 w/b ratio. An inverse relationship was found between Wenner probe resistivity and the diffusion coefficient obtained from the diffusion-based model. Concrete resistivity measurements from the Wenner probe technique have a potential of being used to estimate chloride diffusion coefficients in concrete but more studies are still required.",
